Representation of Corrective-Switching Sequences by Markov Models for Network Reliability Evaluation

G. Theil (Austria)


Reliability, Markov models, simulation, corrective switching.


A methodology for reliability evaluation of electrical networks by application of extended Markov models is presented. Failure effects which can be relieved by a complex sequence of switching actions are handled by adding additional states to the conventional Markov model. The feasibility of the method will be demonstrated for a real-life industrial-type medium voltage network by assessing the reliability-related effects of different planning concepts for additional supply points.
